If I use it and in case any bugs, will they still be taken care of and fixed by author
I doubt that. Check the license attached with the article and/or the source code and then proceed. In most cases, you will be on your own, and the author will (shall) take no blame for anything that happens, neither will (shall) CodeProject.
Secondly, please write this post under the article itself. We have no idea which article/post you are referring to, and neither will the author be notified. If you post this under their profile, they will get an idea that someone needs a help, and they will explain this better.
Who knows they just might be able to help in case of problem — as in an open source project somewhere on GitHub. ;-)
